straf errar SANITARY PROTECTOR FOR I-IEADRESTS.

Application filed April 12,1921.V

To all whom# may concern: Be it known that I, JAivrns L. CARMoNY, a citizen of the United States, residing at Bah timore, in the State of Maryland, have invented certain new and useful Improvements in Sanitary Protectors for Headrests; and I do hereby declare the followingl to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

My invention relates to sanitary protectors for head-rests. l

Among the objects of my invention are: To provide a protector, for use on headrests of dental chairs, or other chairs, where hygienic conditions are essential, so arranged that a clean place for the head of each occupant of the chair can be provided.

ATo provide a protector that can be quickly and easily applied to the head-rests of the above type of chairs and that can also be "quickly removed for a purpose hereinafter `explained:

In the drawings: Figure 1 is a view looking from above the back of a chair, not shown, showing' my im-A proved sanitary protector applied to said head-rest, and the back portion cfa head in contact with said rest in dotted lines.

Fig. 2 is a view lookingin the direction of the arrow 2 in Fig'. 1, the element of the head-rest at the right of Fig. 1 being omitted. v, Y

Fig. 3 is a partial section along' the line 3--3 in Fig. 1, looking in the direction of the arrows. In this view, the top sheet of the plurality of the leaves of paper comprised in my improved protector is shown pinched together near the centre for the purpose of removing same.v

In the drawing:

10 is a head-rest support secured inthe usual manner to the back ofv a chair, not shown, and having attached thereto the head-rest pads 11-11, said pads being of the type well known in the art. Such pads,

while providing` a comfortable support for the head, are not in accord with modern hy- Zrienic principles, inasmuch as the heads of all occupants of said chairs are'placed upon the same portion of said head-rests.

This disadvantage is overcome by my sanitary protector, in which I provide thin Serial N0.. 460,646.

sheets of paper 12, superimposed upon each other and placed upon the top surface of sald pads. Said sheets are made thin to obviate bulkiness, but are of such texture as to resist the absorption ofl oily matter from they head, thus preventing contamination of the remaining sheets of paper.

The sheets 12 are held in position on the top surface of said pads by a retaining ring 13, which is sized and shaped at one edge to fit the pad 11 and at the other edge is shaped 65 to extend over the outermost sheet of the sheets of paper 12, thus holding the latter firmly in place upon the rest 11. In order to secure said retaining ring, springfasteners 14-14 are attached by their ends to screws 15-151515 iiXed in said retaining ring and the middle portions of said fasteners are looped over screws 16-16 fixed in a ring 17, which is adapted to lit the lower portion of the pad 11. Since the sole purpose of the ring` 17 is for the support of the screws 16-16, it is evident that said ring may be dispensed with and the screws 16-16 'A inserted directly into the metal portion at the base of the pad 11A without departing from the spirit of my invention.

The device as illustrated isto be adapted to head-rests now in use, but for newly manufactured head-rests, the change above noted can be made.

The method of attaching` and of using my improved sanitary protector is as follows,- only one element of the head-rest being referred to for the sake of simplicity The pad 11 is removed from the support 10, the ring 17 being then placed around the base of said pad and the latter placed again in position. Any desired number of sheets of paper 12, cut to an appropriate size and shape, are then placed upon the top surface of said pad, the ring 13 placed thereupon. and the middle portions 18-18 of the spring fasteners 14-14- are looped over the screws 16-16. The pressure of the springs 1st-141- will then hold the ring` 13 securely in place.

After the headrest -has been used, the top sheet ofthe paper 12 may be easily removed by pinching up the centre portion between the lingers, as shown at 19 in Fig. 3.

Thus it will be seen that I provide a protector that can `be readily radapted to any head-rest; that it' afords a complete, sanitary covering for said head-rest, and that it van be quickly removed 'for the purpose of relieving the sheets, :is hereinbeol'e exs plained:

claimzw l. The combination of a head-rest, sheets of paper placed thereon,` a retaining ring having a face comprising` am opening;` less n area than the area of said sheets and spring fastening means for pressing said face to- Wald said rest to hold sald paper 1n position.

2. yThe combination of? :L head-rest, sheets of 'pepe1- plzwed thereon, ii retaining ring; and spring fastening means so arranged tht single sheets .may be removed without disturbing said ring o1' said spring fastening means. i

In testimony whereof, I aflx my signa.-
